A statement issued on Friday by the government’s region five livestock office for Chiang Mai said testing detected the highly infectious canine distemper virus. The outbreak has affected two districts in Chiang Mai — the mountainous regions of Mae Rim and Mae Taeng. The park where the deaths occurred could not be reached for comment on Saturday. A total of 147 of the zoo’s 441 tigers died or were euthanised to prevent the virus from spreading further. Authorities in Chiang Mai are continuing to investigate the latest outbreak.
